Build Idaho's 2026 guide put the 2025 new-home median near $623,000, driven largely by new river-adjacent construction.
What's different about decks in Garden City?
- Floodplain first. Garden City reports roughly 1,700 properties in the regulatory floodplain and notes that the Boise River reaches flood stage at the Glenwood Bridge, about 7,000 cubic feet per second, once every five years on average. Work in the floodplain needs the city's floodplain development review, so a riverside deck starts with the flood map.
- Riparian rules apply near the water. The city defines a riparian area along the Boise River and its tributaries, measured 25 feet from the riverbank where there is no greenbelt path, and asks owners to check regulations before building or landscaping there.
- Infill lots are tight. Narrow side yards, close neighbors and new two- and three-story homes push decks upward, which brings guard height, stair landing space and privacy screening into the design early.
- Building permits are submitted to Garden City even though SAFEbuilt and the Idaho Division of Occupational and Professional Licenses perform plan review and inspections, and complete applications with fees are required before routing.
Garden City lies a few miles from the Boise Air Terminal and shares its 108 freezing nights a year, but river-bottom lots stay damper and shadier under cottonwoods, so mildew-resistant decking and good airflow under the frame matter more than on the bench above.

Garden City deck questions
- Do you build decks in Garden City?
- Yes. We work on riverside infill, older homes and newer townhome-style builds across Garden City. Most projects start with the floodplain and riparian questions, then move to a compact composite deck or raised platform that fits a tight lot and holds up to river-corridor shade and debris.
- Does a deck in the Garden City floodplain need extra approval?
- Often, yes. Garden City directs anyone doing work within the floodplain to its floodplain development requirements, and roughly 1,700 properties sit in the regulatory floodplain. We check the flood map for the lot before design and build the review time into the schedule.
- Who reviews deck plans in Garden City?
- Permits are submitted to Garden City Development Services, which routes them to SAFEbuilt and the Idaho Division of Occupational and Professional Licenses for plan review and inspections. Applications must be complete with fees paid before routing begins, and electrical work for deck lighting or a hot tub is permitted separately through the state.
